Bar Pressure Vent
The Bar Pressure Vent (BPV) is designed to achieve a differential pressure between the
formation and tubing string. This tool safely allows a differential pressure in wells with
existing open perforations or in unperforated wells. The BPV is an internal sliding-sleeve
tool, actuated by pressure in the tubing. It is run between the packer and the guns.
Features and Benefits
The BPV
• Offers an inexpensive way to create the necessary underbalance
• Allows the hole to be totally contained at the wellhead before the surge
• Once the port is opened, the sleeve is locked in place
• Can be run with any packer
• Does not rely on tubing manipulation; hydrostatic pressure in the tubing is the only
force required
Operation
The BPV consists of a ported housing and a sliding sleeve. The sliding sleeve is isolated from
the tubing pressure by a break plug with a hollow center.
The BPV is activated when the detonating baris dropped through the tubing and shears the
hollow break plug. This action allows the pressure in the tubing to force the sleeve upward,
uncovering the ports. A lock ringlocks the sleeve open. The detonating bar continues
downward to strike the firing head.
HAL10565
If you wish to open the vent before dropping the detonating bar, you can drop a special tube
that will open the vent and not fire the guns. When the bar is dropped, it will pass through
the tube and fire the guns.
